Title: Charged particle beam control method
Inventor: TAMURA HIFUMI
IPC: H01J37/252
Filed: 1984-03-05
Abstract: PURPOSE:To perform observation of the specimen surface and analysis simultaneously by taking positive and negative beams alternatively as the primary charged particle beam while detecting the positive or negative ion selectively as the secondary charged particle signal to be emitted from the specimen. CONSTITUTION:Positive and negative pulse voltage are applied onto a charged particle source 1 such as a duoplasmatron encapsulated with argon to produce a positive ion beam of anode element and an electron beam of cathode element alternatively as the primary charged particle beam 13. Then it is irradiated alternatively onto a specimen 9 through a deflection electrode 15, a focus lens 5, an iris 2 and a beam separation iris 16 to detect the polarity of secondary charged particle flow 14 selectively through a deflection electrode 17 thus to display the secondary ion image and the secondary electron image simultaneously and independently onto CRT 12, 12'. Consequently, highly efficient observation of the specimen picture image and analysis of the specimen element with high resolution can be realized while the image observation and analysis can be performed simultaneously.

Title: Film making die
Inventor: KURATSUJI TAKATOSHI
IPC: B29C48/95
Filed: 1987-02-25
Abstract: PURPOSE:To manufacture a film where a lubricant is contained on the surface or the vicinity of the surface at a high rate, and is present evenly in a widthwise direction, by providing through insertion a parabolic and flat-platelike flow resistance control plate extending over about the whole width of a slit within a slit part of a die. CONSTITUTION:A flow resistance control plate 4 is provided so that it is ejected in a flowing direction of a polymer in a parabolic state in a size extending over about the whole width of a die 1, and a flow of the polymer on the inside of a slit 3 is divided practically into two. The polymer divided into two within the slit meet again at the tip of a part discharged through a discharge surface of the die of the said control plate 4 and become the one polymer flow. With this construction, the flow of the polymer coming into contact with the control plate 4 becomes extremely slow and this delay becomes remarkable especially at a discharge part through a discharge surface 5 of the die of the said control plate 4. Therefore, it becomes possible that a lubricant is distributed unevenly on the surface layer of the film and that a lubricant distribution is made uniform in a widthwise direction.

Title: Operation method of fuel cell
Inventor: SEGAWA NOBORU
IPC: H01M8/04
Filed: 1984-03-06
Abstract: PURPOSE:To make possible operation of fuel cell for a long time by performing one or more power generating method which changes active materials to be supplied to positive and negative electrodes of fuel cell to change positive electrode and negative electrode. CONSTITUTION:Since oxidizing agent electrode of fuel cell is kept to high potential in power generation, coagulation of catalyst occurs with the passage of time and output is decreased. Since the potential of fuel electrode is lower compared with that of oxidizing agent electrode, coagulation of catalyst is difficult to occur. The coagulation of electrode catalyst causes decrease in catalyst surface area and results in the output drop of cell. When fuel electrode catalyst which is difficult to coagulate is used as oxidizing electrode, the cell can be operated for a long time without voltage drop. Even if the electrode catalyst which is coagulated by using as oxidizing agent electrode is used as fuel electrode, it can be used as active electrode catalyst because fuel electrode reaction is faster than oxidizing agent electrode reaction.
